Android-仿真器启动卡住“QEMU管道设备:rw，wait_event错误”

Question

我正在尝试编译金鱼android内核，并使用模拟器运行它。我做了谷歌告诉我的每件事。( Android内核编译和测试android Emulator，如何编译android goldfish 3.4内核并在仿真器上运行)。昨天，我按照提示，成功地使用了android仿真器。但是今天当我再次启动仿真器时，它不工作了。启动日志显示卡住"QEMU管道设备:rw，wait_event错误“，谁能帮我？由衷地提前感谢。

环境:VMware10、ubuntu14.04，goldfish3.4，ASOP_arm，Android4.4

我自己解决的。出现此错误的原因是android-模拟器的switch参数导致的。所以如果你这样做的话：

root@virtual-machine:/work/android4.4/out/target/product/generic# mv userdata.img userdata.img.bak

然后重新启动模拟器，模拟器就不能使用那个userdata.img了。这一切都是因为userdata.img。这件事的细节我不知道。也许将来会有人告诉我们。
